Ihave been using init.ora to set up the initialization parameters for the database. I do know we can use config.ora as well to maintain some static parameters.

But how does this init.ora knows where the config.ora is located. I mean after the instance is startup with init.ora where the instance goes to get further parameters which have been specified in config.ora.

Is there any parameter in init.ora to specify the location of config.ora for the given instance?.
